PATENT N LEE MONTGOMERY, OF .EUNNELL, MARYIIAND;

BRICK-MAGHINE.

Specification of Letters Patent No. 3,167, dated July 8,1843.

To all whom t may concern: l

Be it known that I, LEE MONTGOMERY, of Tunnell P. O., in the county ofAllegany and State of Maryland, have invented a new and usefulImprovement in Machinery for Making Bricks; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had'to the accompanying drawing, which forms aA part of thisspecification, in which- Figure l, is a geometrical side elevationshowing the gearing. Fig. 2, is a vertical Section through the center ofthe molds; Fig. 3, section in perspective of levers (b4) and cam 76,'Fig. 5, mold separate in section showing the lever (b4) and bottom (b)The nature of my invention consists in combining a wheel, the peripheryof which is indented with a series of brick molds, with an antagonistwheel having projections on it, which shall force the clay into themolds; said projections being sufficiently convex to make the `face ofthe brick next it straight.

To enable others to construct my machine I will describe its differentparts.

A, A, is a suitable frame to contain the machinery, and should be bracedand strengthened to suit the purposes of the builders. In this frame issuspended a vertical wheel (a), the Width of which should be such, as toadmit a brick lengthwise and have a flange (a) project up on each side,all around; between the spaces allowed for the width of the bricks to bemade, are divisions (o), these divisions do not extend out as far as theflanges, and the outer part of each is chamfered oft1 on each edge, therest (which is the thickness of the brick) being' straight, and parallelwith the side of the next division; this form makes the sides of themold and above, or outward, a fiange mouth to it. The bottom of thesemolds (b) is made movable and rests, when the mold is full, on a solidring (b2), through a hole in which, a piston rod (b3) runs, that j thebottom is fixed to; this rod is connected with a lever b4) the end ofwhich projects beyond the frame, for a purpose hereafter described theinner ends of these levers are shown. Over the center of the mold wheel(a) there is a hopper (c) of the same width, and covering about oneeighth of the periphery, for holding the clay, one end of this hopper isa firmly fixed board, the other, a movable board (c) made to slide upand down, and in anangular direction; just behind this slide, outsidethe hopper, a smooth cylindrical roller (c2) is placed, of a properlength to work between the flanges (a) and down, nearly to touch thedivisions between the mouths of the molds. On a horizontal line with theaxle of the mold wheel, there is another wheel (al) having projections((Z) from its periphery that just fit into the mouths of the molds onthe wheel (c) these projections are suliciently convex on their face, toform a straight line on the surface of the brick when it has passed onit. These wheels are geared together; a pinion (e) on the axle of wheel(d) working into a spur wheel (f), on the mold wheel (a), and anotherpinion (g), also gearing into the wheel (f) which is on the axle ofroller (c2). Under the lower part of the mold-wheel there is a roller(7L) over which an endless apron (L) passes and extends out to anotherroller (h2). These are turned by a pinion (i) on the axle of roller(71,) which meshes into wheel (f). The driving power is connected withthe axle of wheel (CZ) by which the machine is put in motion. At a pointbelow the axle of the bold wheel, an inclined plane (shown in dottedlines in Fig, 2) is fixed to the frame; that the levers (b4) beforenamed strike, as they come round, and by lifting the outer end of them,the bottom of the mold attached to them is forced forward to the mouthof the mold which flares each way and consequently the brick isreleased, and falls onto the apron. After the lever (b4) passes the cama spiral spring, which is wound around the rod (3) aflixed to the bottom(,79) brings it into place again; the levers are steadied by passingthrough mortises in the rim of the moldwheel, which is extended inwardfor that purpose. In one end of each mold there is a hole (n), throughwhich any superfluous amount of clay can be disgorged, and the action ofthe machine remain unimpeded.

Having thus fully described my invention I wish to have it understoodthat I do not claim placing molds around the periphery of a wheel. But

)What I claim as my invention and desire to secure by Letters Patentisl. The molds, having Haring mouths so as readily to admit theprojections on the wheel (el), to work into it, and deliver the bricksfreely, placed around the periphery of Jche wheel, constructed andarranged as 3. Lastly I claim in combination With the Y herein set forthabove, the sliding board (c) and roller (02) Q. I also claim thecombination of the in the manner herein made known.

Wheel (cl) having projections (d) 0n it, L. MONTGOMERY. 5 With Convexsurfaces with the molds con- Witnesses:

structed, arranged, and combined, in the J. J. GREENOUGH,

manner and for the design above described. JOHN HITE.
